Troy Jackson has effectively clinched the Maine Democratic Senate nomination after dominating county-level delegate elections across the state over the weekend, securing 480 of 601 delegates—well over the 301 needed to win at a July 25 nominating convention.
The former state Senate president claimed 96 percent of the delegates selected in 16 county meetings, with his preferred candidates sweeping several counties entirely. Jackson’s commanding performance came after three major rivals—Maine Secretary of State Shenna Bellows, former state public health official Nirav Shah, and former congressional staffer Jordan Wood—withdrew from the race on Sunday.
The delegate selection process was unprecedented in Maine politics. Rather than a traditional primary, the state Democratic Party organized a compressed nominating convention to replace Graham Platner, who won the June 9 primary but withdrew on July 8 following sexual assault allegations he denied. The party held county meetings over two days this weekend, with 17,279 Democrats casting ballots—85 percent of those registered to participate.
Jackson, a 58-year-old fifth-generation logger from Allagash in Aroostook County, spent two decades in the Maine legislature, including six years as Senate president. He had placed third in the gubernatorial primary earlier this year but had been endorsed by Vermont Senator Bernie Sanders. At a Sunday rally in Sanford before the York County delegate meeting, Jackson told supporters his campaign was rooted in working-class concerns. “This movement has always been about working people having the opportunity, showing up, and fighting for what they deserve,” he said, adding that he was running for loggers, shipyard workers, nurses, and immigrant families.
Jackson’s organizing operation proved decisive. He distributed complete slates of preferred delegate candidates and instructed supporters to vote for every name on those lists. In Knox County, Sagadahoc County, Oxford County, and several others, his slates swept all available delegate seats. Even in York County, Maine’s third-largest, he won 83 of 84 delegate slots.
Bellows, Shah, and Wood all cited the need for Democratic unity against Republican incumbent Susan Collins, who has held her Senate seat since 1996 and is seeking a sixth term. “The most important thing we can do in this moment is unite to defeat Susan Collins,” Bellows said in a statement. Shah added: “Susan Collins, Donald Trump, and Senate Republicans are banking on disunity and frustration from Maine Democrats to try and win this seat, and we are not going to give them that.”
Jackson will face a steep challenge in the general election. Collins currently has an $11 million war chest, according to the latest Federal Election Commission filings, and has defeated well-funded Democratic opponents of all stripes for three decades. More immediately, Jackson has less than four months from the July 25 convention to Election Day on November 3—a compressed timeline that limits his ability to introduce himself, particularly in southern Maine where he is less known. “I’m six hours away from my home. And as we know, the state legislature means nothing. Nobody’s following it,” Jackson acknowledged to reporters, saying he would need to work quickly to build name recognition downstate.
